An effective strategy for walking over rough terrain, flat plane, and wreckage includes transitioning from quadrupedal to bipedal locomotion. In this study, we designed a trunk mechanism that provides successf...
Most of the long-reach inspection devices developed so far have a limitation in the reduction of their diameter when their length is increased. This limitation is due to the technology used to provide the actu...

Hydraulic actuators have high power-to-weight ratios, making them suitable for high-power robotic applications such as in walking robots and construction machines. However, large frictional forces in hydraulic...
Recently, researches on electric vehicle are focused on motion control and state estimation. These works require a model that imitate a real vehicle as close as possible. We propose in this paper a signal hard...
A mechanism that allows a robotic arm to quickly grip various forms of objects at disaster sites will enhance the mobility of rescue robots by keeping their bodies stable and maintaining manipulability for tar...
